Question

An unknown quantity of noble gas Xenon (Xe) is added to a cylinder containing a mixture of noble gas helium (He) and Argon (Ar). In the cylinder, the partial pressure of He is 3.10 atm and Ar is 1.20 atm. After the addition of Xe , the total pressure in the cylinder is 5.80 atm. What is the partial pressure of Xe gas in the cylinder? Name the gas law. Show the table of the given values. Show the equation of the gas law and rearrangd Eq. Solve the problem with correct units and significant figure

Explanation / Answer

Given data;

PHe = 3.10 atm

PAr = 1.2 atm

Total pressure P = 5.80

Unknown

PXe = ?

Theoretical model

According to Dalton’s law the partial pressures are additive:

P = PHe + PAr + PXe

PXe = P - PHe - PAr

Calculation

P = 5.80 atm – 3.10 atm – 1.20 atm = 1.50 atm
